90º Accuracy Between Vertical Beams
Checking 90º accuracy requires an open floor area
at least 33’ x 18’ (10m x 5m). Refer to Fig.e A for the
position of the laser at each step and for the location of
the marks made at each step. Always mark the center
of the beam’s thickness.
1.
Place the laser on a smooth, flat, stable surface
that is level in both directions.
2.
Move the Power/Transport Lock switch to the right
to turn the laser ON.
3.
Press to turn on the side vertical beam.
4.
Mark the center of the beam at three locations
(
a
,
b
,
c
) on the floor along the side laser line.
Mark
b
should be at the midpoint of the laser line
(Fig.
G 1
).
5.
Pick up and move the laser to
b
.
6.
Press to turn on the front vertical beam too
(Fig.
G 2
).
7.
Position the front vertical beam so it crosses
precisely at
b
, with the side beam aligned with
c
(Fig.
G 2
).
8.
Mark a location
e
along the front vertical beam at
least 14’ (4m) away from the unit (Fig.
G 2
).
9.
Rotate the laser 90º so the side vertical beam now
passes through
b
and
e
(Fig.
G 3
).
10.
Directly above or below
a
, mark
f
along the
front vertical beam.

Vertical Beam
Checking the vertical (plumb) calibration of the
laser can be most accurately done when there is a
substantial amount of vertical height available, ideally
30’ (9m), with one person on the floor positioning
the laser and another person near a ceiling to mark
the position of the beam. It is important to conduct
a calibration check using a distance no shorter than
the distance of the applications for which the tool will
be used.
1.
Place the laser on a smooth, flat, stable surface
that is level in both directions (Fig.
F 1
).
2.
Move the Power/Transport Lock switch to the right
to turn the laser ON.
3.
Press and to turn on both vertical beams.
4.
Mark two short lines where the beams cross
a
,
b
and also on the ceiling
c
,
d
. Always mark
the center of the beam’s thickness (Fig.
F 2
).
5.
Pick up and rotate the laser 180º, and position it
so the beams line up with the marked lines on the
level surface (
e
,
f
) (Fig.
F 3
).
6.
Mark two short lines where the beams cross on
the ceiling
g
,
h
.
7.
Measure the distance between each set of marked
lines on the ceiling (
c
,
g
and
d
,
h
). If the
measurement is greater than the values shown
below, the laser must be serviced at an authorized
service center.
